How is a smartphone different from a cell phone，and what makes it so smart? To understand this，we should start with a history lesson． 1. Cell phones were used for making calls while PDAs could store information and a to-do list，and could be linked to your computer．Then PDAs added cell phones’features，while cell phones added PDA-like(and even computer-like)features．The result was that the smartphone came into being．

Here are some features of smartphones．

Operating system． 2. In general，a smartphone will be based on an operating system that allows it to run applications．For example，Apple’s iPhone runs the iOS，and BlackBerry smartphones run the BlackBerry OS．

QWERTY Keyboard．A smartphone includes a QWERTY keyboard．This means that the keys are laid out in the same manner they would be on your computer keyboard，where you don’t have to tap the number 1 to enter an A，B or C．

These are just some of the features that make a smartphone smart．5. What makes a smartphone today may change by next week，next month or next year．Well，a smartphone of the future may be in your brain．

What is a lifestyle and how is that different from a life? A lifestyle is about brand names and buying identity or fame. Lifestyle gives a false sense of peace and acceptability that comes from others recognizing what you’ve bought into (as well as bought). If your car, clothes, and home are expensive, you’re sophisticated(世故的) and stylish. If you have the right kind of job or go to the right social gatherings, then you receive the insincere approval of others. This means that your self-esteem(自尊) is always at the mercy of others, with no appreciation of you as an individual.

A life, on the other hand, is very different. A life is what you lead when you know what matters most to you. It is very simple and comes from being connected to what you know is important and being willing to put that first, no matter what others may think. When you create a life vs. a lifestyle, your self-esteem comes from what’s inside you, not what others think about you.

Lifestyle is expensive financially and personally, because it costs a great deal to keep up appearances and do what you think is socially acceptable. A life is not expensive. Rather than using personal or financial resources, a life generates energy and staying power. It’s about liberating yourself from the mindless consumption that society expects. It is about making the choices that are in line with your values, instead of using up your bank account or energy for no heart-driven reason.

How can you make the change? Understand the difference between a life and a lifestyle. Analyze your current lifestyle to see what is costing you in money, time, stress, and energy to maintain it. Let go and make room for what is really important to you, what supports you and brings you joy. Remember who you are from within, not what you own!

1.Which of the following examples best explains “what is life about”?

A. We work long hours in a job that we do not enjoy.

B. We focus on what we wear, or what kind of car we drive.

C. We find out what our true beliefs and values are and choose to live by these.

D. We think that how others see us is more important than what we think of ourselves.

2.What method does the author use to explain his opinion in the third paragraph?

A. Making comparison.　　 B. Giving an example.

C. Giving a definition.　　 D. Giving a reason.

3.To make the change, we need to______________________.

A. be directed from within　　 B. be directed from outside

C. be driven by social values　　 D. be driven by others’ opinions

4.What is the author’s purpose of writing this passage?

A. To describe what life is.

B. To introduce what lifestyle is.

C. To promote life instead of lifestyle.

D. To tell the differences between life and lifestyle.

A new phone app uses shaking from smartphones to warn people about earthquakes. The new app is called MyShake, which is the work of four researchers at the University of California. Berkeley.

Smartphones are equipped with accelerometers(加速器). MyShake uses phone accelerometers to measure seismic (地震的) activity. It has been programmed to know the difference between normal activity and earthquake movement. The software developers say their app is right 93 percent of the time. A smartphone sends seismic information to the app developers. If the developers receive several warnings from one area, it recognizes that an earthquake may be taking place or will take place soon. Using information sent from the app, the network then judges the location and strength of the quake in real time. MyShake can record 5.0 earthquake at distances of 10 kilometers or less.

MyShake uses very little power, according to its developers. Only when seismic activity is sensed by the app does it become active and sends data to the network. The app works best when your phone is resting on a flat surface, like a table.

The developers hope that MyShake can add to information collected by the U.S Geological Survey. That U.S agency has created the Earthquake Early Warning System, also known as the EEW. The EEW has used sensors for measuring quakes in many areas. In places where no such equipment exists, MyShake may be the only method of early quake detection (发现). The app also shows ways to stay safer during an earthquake. The developers say it will become more effective as more people use it.

The developers say they hope to add a feature that will warn people about possible tsunami after an earthquake.

1.The new app

A. is a kind of accelerometer.

B. feels earthquakes through smartphones.

C. is developed by the U.S Geological Survey.

D. predicts possible tsunami after an earthquake.

2.What is the second paragraph mainly talking about?

A. How MyShake works.

B. What seismic activity is.

C. Why MyShake is developed.

D. When accelerometers record earthquake.

3.We can infer that MyShake

A. docs not work when the spartphone is in the pocket

B. sleeps while there is no shaking of the earth’s surface.

C. guides people how to survive when many people use it at the same time.

D. recognizes an earthquake when it receive the information from other sensors.

4.The new app developers hope to

A. use the information by the U.S Geological Survey to better MyShake.

B. unite the U.S Geological Survey to combine the EEW and MyShake.

C. help the EEW detect earthquakes somewhere.

D. improve the EEW.

How do you kill your time when you go to work? Most of us stare at our cell phones, and refuse to make eye contact with others. We just read, chat with others online or play games online. Or maybe we’re using the time between stops to do our makeup, catch up on emails, or read a few chapters of a book. However, Dina Alfasi takes a very different approach.

Each day she has to travel hours on buses and trains to get to her engineering job at a hospital in Israel. Rather than look at her cell phone in silence, she uses one very special way to have connection with strangers. It is portraits of the people she meets on public transport every day that she is taking. The photographs catch those quiet and personal moments of people readying themselves for the day ahead. Some people lean (倚靠) their head against the window and go to sleep, some stare into space and have a daydream, and others sit quietly to read their documents or books. Each picture catches one tiny moment in people’s lives, ripe with potential for your imagination. It is wonderful for her to look at someone’s commute (上下班) and make up an entire story about the rest of their daily existence, from the father travelling with a baby to the woman welcoming a change.

“What inspires me very much are the little moments that happen every day,” Dina told My Modern Met. “My work is to tell stories through a single portrait, and it proves that all you need is just to look around and find those magic moments.”

1.What will most people do when going to work?

A.Enjoy reading a book loudly.

B.Make eye contact with others.

C.Have face-to-face talks with others.

D.Concentrate on their mobile phones.

2.What makes Dina different from others?

A.Staring into the space and having a daydream.

B.Leaning against the window and relaxing herself.

C.Using her mobile phone to appreciate pictures she draws.

D.Drawing people while travelling on buses and trains to work.

3.Which word can best describe Dina Alfasi?

A.Cool. B.Careful.

C.Generous. D.Considerate.

4.What is the main idea of the text?

A.Little moments make Dina special.

B.Cell phone is used to take special portraits.

C.Dina takes portraits of others when commuting.

D.People go to work with different ways to kill time.
